Ranked #116 car in the UK · Saloon · 4,569 units sold last year

Mercedes-Benz C-Class

The Mercedes C-Class spans the W205 (2014-2021) and the screen-led W206 (2021 on), the compact executive saloon pitched squarely at the 3 Series and A4. It leans toward comfort and a luxurious, S-Class-in-miniature cabin over outright driver appeal. UK cars are mild-hybrid petrols, diesels and a long-range C300e plug-in hybrid that can cover serious distances on electric alone.

How these figures are sourced the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

Forecourt score

Value 43 · Reliability 19 · catalogue percentiles

The Mercedes-Benz C-Class holds its value about averagely and costs about average to run. Its MOT-based reliability is average — an MOT score of 65/100, ahead of 42% of the cars we track. On three-year value retention it ranks better than 43% of models.

The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20) — the from-new ownership picture. Higher is better; running cost is not yet folded in.

Safety rating

Euro NCAP's independent crash-test rating for the Mercedes-Benz C-Class, from its 2022 assessment.

5/5
TEST YEAR2022
Current rating · valid to 2028

The passenger compartment of the C-Class remained stable in the frontal offset test.

Independent crash-test data from Euro NCAP. Star ratings reflect the test protocol of the year shown — newer protocols are stricter, so a 5-star from 2024 represents a higher bar than a 5-star from 2014. Euro NCAP ratings run for six years from publication; a lapsed rating means the protocol has moved on, not that the car performs any worse than it did on test.

MOT outlook

How this model fares at its MOT as it ages — from 277,215 real DVSA test records.

MOT pass rate by age

A 3-year-old C-Class passes its MOT 88.3% of the time; by 25 years that has slipped to 74.6%. The y-axis is zoomed to this model’s range so the trend is readable.

Longevity

Survival by registration year

Each point is one registration cohort. Older cars on the left, newer on the right. A flatter line means the model holds up over time; a steep drop means cohorts disappear from UK roads faster.

What fails at the first MOT

The defect categories a C-Class registered 2020–2023 fails on at its first MOT, from 15,438 first tests. Every car here is the same age and the same generation, so these are the faults that show up first - not the wear a high-mileage older example collects.

Things owners say

  • 01The C220d diesel is the mile-eater; the C300e PHEV has an unusually large battery for genuine 60-mile-plus EV range.
  • 02Early W205 infotainment and trim feel dated next to the W206's portrait touchscreen.
  • 03The W206's all-digital dashboard is striking but buries simple functions in menus - try it before you buy.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Mercedes-Benz C-Class, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

Theft risk

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.

Whole-car theft

Higher

Higher-value cars like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.

Parts theft

Higher

Hybrid versions are a catalytic-converter target — a hybrid cat is rich in precious metals and can be cut out in about a minute.

Worth doing

  • Keep keys in a Faraday pouch and away from the front door to block relay attacks.
  • A catalytic-converter guard or forensic marking makes a hybrid far less appealing to cut.
  • A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.

Clean-air zones

Whether driving a Mercedes-Benz C-Class into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.

Company car tax

What HMRC's Benefit-in-Kind charge looks like if you ran this Mercedes-Benz C-Class as a company car, by tax year and income-tax band. Calculated from a CO₂ of 157 g/km and a WLTP electric range of 47 miles, using £53,000 as the P11D value.

Servicing & the dealer network

How well-supported Mercedes-Benz is across the UK — a practical read on how easy servicing, parts and warranty work will be to find.

Franchised UK dealers

~125

Large network

Premium mainstream

Network size relative to the UK's largest (Mercedes-Benz is 2.8% of all franchised outlets)

Servicing, parts and warranty work are easy to find UK-wide, and most independent garages know the brand well — which keeps maintenance competitive.

For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.

Approximate figures, curated from public UK industry sources (NFDA, Car Dealer Magazine). Franchised networks shrink year on year — these indicate network size, not an exact count.

Common questions

Mercedes-Benz C-Class, answered from the data

Is the Mercedes-Benz C-Class reliable?
The Mercedes-Benz C-Class scores 65/100 on Forecourt's MOT-based reliability measure, ahead of 42% of the cars we track. That is computed from 277,215 real DVSA MOT test results.
How much does a used Mercedes-Benz C-Class cost?
A 2023 Mercedes-Benz C-Class with around 28,878 miles is worth roughly £23,550 today (typical range £21,250–£25,850). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
How quickly does the Mercedes-Benz C-Class depreciate?
A new Mercedes-Benz C-Class typically loses about 42% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.
What insurance group is the Mercedes-Benz C-Class?
The Mercedes-Benz C-Class sits in insurance group 32 of 50 — the more expensive end of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.
What goes wrong on a used Mercedes-Benz C-Class?
The most common age-related issues we track for the Mercedes-Benz C-Class are: suspension (typically around over 100k miles, £150-£450 to put right); tyres & wheels (typically around over 100k miles, £80-£500 to put right); brakes (typically around over 100k miles, £150-£500 to put right). A full service history and a recent MOT with no advisories are the best protection.
What does the Mercedes-Benz C-Class cost to run?
Expect around 55 mpg combined on the C 220 d AMG Line, £200 a year in road tax, about £290 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.
Is the Mercedes-Benz C-Class ULEZ compliant?
Most petrol Mercedes-Benz C-Classs from 2006 and diesels from September 2015 meet the Euro standards for London ULEZ and other UK clean-air zones, so they are generally exempt from the daily charge. Pure-electric versions are always exempt.
How many Mercedes-Benz C-Classs are on UK roads?
About 342,909 Mercedes-Benz C-Classs are currently taxed and on the road in the UK, from DfT vehicle-licensing data.

Answers are generated from this car's Forecourt data — DVSA MOT records, DfT licensing statistics and our valuation model — and update with the weekly data refresh.
